Kwak Jung

Past Timeline
Kwak Jung served under a different Great Power leader, but died of lung cancer in the early years of the war in 2040. He had died early at 38 years of age. If Kwak Jung had been Kang Chul-In’s subordinate, he would have cured the lung cancer, no matter what stage, and worked Kwak Jung until he died from overwork… but there was nothing to do for one who had already passed. His nickname is "Black Leopard" though he doesn't like it.
